These are examples of a simple device and only one resistive force is provided, so a plurality of exercisers are needed to provide a wide range of exercises. Other devices are known in which a pair of arms are pivotally connected together and the force required to squeeze the handles together can be changed by varying the spring itself, so requiring a plurality of springs to provide a range of exercises. alternatively, it is known to provide a range of adjustment positions so that the resistance providing spring has a variety of positions on the handles. Sometimes such adjustments are made by varying the positions of the pins in the handles, and the pins are moveable between a plurality of holes.

The invention will now be described with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a hand grip exerciser according to the present invention; Figures 2a -2d is a side elevation view, front elevation view, rear elevation view and top plan view respectively of the exerciser; and Figure 3 shows an expanded view of the exerciser.
The invention will now be described in more detail with reference to the drawings Reference is now made to Figure 1 which shows a perspective view of the exerciser 10, constructed in accordance with a preferred embodiment of the invention, in its normal state. The exerciser 10 includes two handgrips 12a and 12b forming respective arms. At a first end of each of the handgrips 12a, 12b are respective handle parts 14a, 14b. The handgrips are connected together in a central region. Bearing covering plates 22 (only one of which can be seen in this figure) cover a pivot pin. At second end of each of handgrips 12a, 12b, remote from the handle 14a, 14b are respective mounting heads 26, 30. The exerciser 10 includes resistance providing structure (not shown in these figures) to provide a resistive force against which the user will exercise by squeezing the handle parts 14a, 14b together. On mounting head 30 an adjustment assembly is provided to enable easy adjustment of the resistance of exerciser 10 against the pulling together of the two handle parts 14a 14b, as will be described in more detail below.
Figures 2a -2d show side, front, and rear elevation views and a top plan view of the exerciser10. Arms 12a and 12b are interconnected by a pivot means covered by covering plate 22 The resistive structure is mounted in the mounting head portions 26, 30 as will be explained in more detail below. Adjustment assembly is provided on the mounting head 30 to enable easy adjustment of the resistive force applied by the resistance element.
Figure 3 shows an exploded view of the exerciser 10. Pivotally connected arms 12a, 12b each have respective handgrip regions formed on handle parts 14a, 14b located at a respective first end of the arms 12a, 12b. Each of arms 12a, 12b extends to respective central regions 16a, 16b which in turn extend to and support respective bearing surfaces 18a, 8b. The bearing surfaces I 8a, I 8b surround a mounting hole, formed through each of bearing surfaces 18a, 18b, through which a pivot pin 20 passes. The bearing surfaces 18a and 18b engage with each other and are adapted to allow the arms 12a, 12b to be pivotally interconnected by pin 20 passing through bearing surfaces 18a, 18b. Arms 12a, 12b rotate around an axis defined by a longitudinal axis of the pin 20. The pin 20 and bearing surfaces 18a, 18b are covered by covering plates 22 to assist in protecting the pin 20 and bearing surfaces 18a, 18b from damage and the ingress of unwanted materials.
At a second end of each of the arms 12a, 12b remote from the handgrip region are mounting means for mounting the resistive element 24. The first arm 12a includes a first mounting head 26. The mounting head 26 supports a securing pin 28, which in turn provides a mounting part for securing a first end of the resistance element 24. In this embodiment, the resistive element 24 is a helical coil spring, having a first end of the coil formed into a loop shape which engages with the securing pin 28 to hold the spring in place in the mounting head 26. The second arm I 2b includes a second mounting head 30 for mounting a second end of the spring 24. Mounting head 30 includes an adjustment assembly. The adjustment assembly includes a threaded screw 32 having a longitudinal axis about which the screw rotates in known manner and a head end 36 which is formed to make it easy to rotate the screw 32. Such a head end 36 may be formed with a grip surface such as a knurled edge or circumference, as is well known in the art or other convenient form of grip.
The screw 32 engages with a threaded nut 38, secured in the mounting head 30 against rotation with the screw, along a longitudinal axis of threaded nut 38. In the present embodiment the threaded nut 38 is secured in the mounting head 30 by one or more pins 40. A second end of the screw 32 includes a rotatable coupling element 34, a first part of which is attachable to the resistive element 24 and a second part which is rotatably connected to the screw 32, so enabling the screw 32 to rotate without also causing the resistive element 24 to be rotated at the same rate as the screw 32 By this structure the screw 32 can be rotated around its longitudinal axis and so move along the longitudinal axis to change the position of the screw 32 in the threaded nut 38 and so also change the length of the resistive element 24 without rotating resistive element 24 Rotating the screw 32 will move screw 32 along its longitudinal axis relative to nut 38 and so change the length of the spring24, and, as a result, increasing or decreasing the resistive force applied against rotation of the handles around the pivot point. From this is it can be seen that the resistive force applied by the spring to any movement of the handle parts 14a, 14b around the pivot pin 20 can be easily adjusted. An additional advantage of the present embodiment is the adjustment can be done in fine, if not infinitesimally fine steps.
Alternatively, the spring 24 could be replaced by an elastomeric element, such as a rubber or synthetic compound, provided with anchoring points at each end.at a first end, the anchoring point could be secured to an alternative form of securing pin 28. At a second end, the elastomeric element could be secured to the resistance attachment means by a rotatable coupling similar to that described above.
